摘要 | PURPOSE:To obtain a green visible light laser by holding an active layer consisting of a direct transition type substance, film thickness thereof is approximately the same as a de Broglie wavelength of carriers, by plural layers, conductivity thereof differs to each other, and lattice-aligning the active layer on a substrate. CONSTITUTION:A ZnSwTe1-w layer 2, conditions for lattice-alignment thereof are very excellent and a band gap thereof is large, is crystal-grown on an N type GaAs substrate 1 in the thickness of approximately 2-3mum, and an active layer 3 consisting of direct transition type (AlxGa1-x)y In1-yPzAs1-z (0<=x, y, z<=1), film thickness thereof is approximately the same as a de Broglie wavelength of carriers, is formed on the layer 2 through a molecular-beam epitaxial method. A layer 4 of the qualiy of a material the same as the layer 2 is formed in the thickness of approximately 2-3mum, an N type GaAs layer 5 is formed in approximately 1mum, and a P type impurity is diffused in the width of approximately 5mum in a striped shape to form a diffusion layer 6. Then, ohmic electrodes 7, 8 are formed. |
其他摘要 | 用途:为了通过保持由直接过渡型物质组成的有源层获得绿色可见光激光,其膜厚度与载流子的德布罗意波长大致相同,通过多层,其导电性彼此不同,并且晶格- 将有源层对准基板。组成:ZnSwTe1-w层2,其晶格排列的条件非常好,其带隙大,在N型GaAs衬底1上晶体生长,厚度约为2-3μm,有源层由直接过渡型(AlxGa1-x)y In1-yPzAs1-z(0 <= x,y,z <= 1)组成的膜,其膜厚度与载流子的德布罗意波长大致相同,形成于第2层通过分子束外延方法。形成与层2相同的材料质量的层4,其厚度约为2-3μm,N型GaAs层5形成为约1μm,并且P型杂质以约的宽度扩散。条形的5μm形成扩散层6.然后,形成欧姆电极7,8。 |
